The all-solid multilayer battery may be produced by depositing, by electrophoresis without any binder, at least one anode layer, at least one electrolyte layer, and at least one cathode layer. The at least one electrolyte layer, and the at least one cathode layer are obtained from a colloidal suspension containing nanoparticles that are not agglomerated with each other to create clusters and remain isolated from each other. A layer of Ms bonding material is then deposited on a surface of the at least one electrolyte layer. Next, two layers from the at least one dense anode layer, the at least one dense electrolyte layer, and the at least one dense cathode layer, are stacked face-to-face to obtain the all-solid multilayer battery having an assembly of a plurality of elementary cells connected with one another in parallel.

According to the invention, the heating means are means of heating by optical radiation (5) and the tool further comprises concentration means (26, 28, 46) able to concentrate the energy of the radiation towards the said object. In that way, the optical radiation is directed at the entirety of the object that is to be pressed but, by contrast, no substantial proportion of this radiation passes outside the lateral edges of this object. A preferred, although not exclusive, use of this tool is the creation of solid-state lithium-ion batteries.

Abstract

A process for fabrication of all-solid-state thin film batteries, may include batteries including a film of anode materials, a film of solid electrolyte materials and a film of cathode materials. Each of these three films may be deposited using an electrophoresis process. The anode film and the cathode film may each be deposited on a conducting substrate, preferably a thin metal sheet or band, or a metalized insulating sheet or band or film. The conducting substrates or their conducting elements may be useable as battery current collectors, the electrolyte film may be deposited on the anode and/or cathode film. The process may also include stacking the sheets or bands so as to form at least one battery with a “collector/anode/electrolyte/cathode/collector” type of stacked structure.
